Question about HP-11C screens Message #1 Posted by Dave Demers on 14 Nov 2006, 8:15 p.m. My wife dropped my HP-11C and cracked the LCD. Sigh... The screen is 3/4 black and has a visible crack. It's serial number is 2320A. My question is would the screen from an HP-12C with SN 2421A be compatible without too much replacement fuss?

Early units had symmetrical silver contacts, later machines had a spring on the left and a gold plated pc board contact on the right. Within the date code range you mention, if both units share the same design battery contacts, the displays are interchangable. Quote: without too much replacement fuss If it's your first time inside a Voyager, it is *not* an easy task. Even after having done dozens of these exchanges over the years, I still dread them, it is one of the most tedious repairs you'll ever encounter.
